Answer:

Multiply both sides by -2 and reverse the inequality symbol.

Step-by-step explanation:

To isolate w, multiply both sides by the reverse of -1/2 (because -1/2*2=1 ), which is -2

When multiplying or dividing by negatives, you must reverse the inequality symbol as well.

Julian has to read 4 articles for school. He has 8 nights to read them. He decides to read the same number of articles each nigh

daser333 [38]

Answer:

a. He will have to read half an article per night

b. Fraction of the reading assignment read each night = $\frac{0.5}{4}=\frac{1}{8}$

Explanation:

Part a:

We are given that:

number of articles to read = 4 articles

number of nights = 8 nights

To get the number of articles that he should read per night, we will simply divide the the number of articles by the number of nights

Therefore:

number of articles to read per night = $\frac{4}{8}=\frac{1}{2}$ articles per night

Part b:

Now, we know that he will read half an article each night from a total of 4 articles

To get the fraction of the reading assignment read each night, we will divide the number of articles read each night by the total number of assignments

Therefore:

Fraction of the reading assignment read each night = $\frac{0.5}{4}=\frac{1}{8}$

Hope this helps :)

Diane is 25 years older than her son Craig. The sum of their ages is 105. How old are Diane and Craig?

ankoles [38]

Answer:

Let Craigs age = x

Therefore Dianes age = 25 + x ( since she's 25 years older)

Dianes + Craigs age = (25 + x) + x = 105 (They said both of their ages sums up to 105)

25 + 2x = 105

2x = 80

x = 40

Craigs age is 40 years old.

Dianes age is 65 years old.
